CHATHAM - A Chatham man who crashed his red pickup on Route 28 on New Year’s Day has been charged with driving under the influence of “bath salts,” according to the Chatham police.

On Tuesday, the Chatham police received a report about a red pickup truck heading eastbound on Route 28 at a high rate of speed with no headlights on. The police found the vehicle at 5:05 p.m. after it had struck a tree and flipped on its side near Victoria Drive.

Kenneth B. Nickerson, 49, of Chatham, found behind the wheel.

After he was treated for minor injuries at Cape Cod Hospital in Hyannis, Nickerson told police he had ingested “bath salts,” according to a press release from the Chatham police.

It is his fourth operating under the influence arrest, police said.

Nickerson is also charged with negligent operation of a motor vehicle, speeding, and other motor vehicle infractions.

The crash was investigated by Chatham Police Officer William Little, who is also assigned to the Cape Cod Regional Law Enforcement Council’s Crash Reconstruction Team.

Though marketed as “bath salts,” the powdery substance is actually made up of synthetic stimulants, according to the U.S. Department of Justice.

People who abuse them have reported agitation, insomnia, irritability, dizziness, depression, paranoia, and delusions. Drugs causing similar effects include amphetamines and cocaine, according to the Justice Department.

Massachusetts lawmakers banned the legal sale of the chemicals in so-called “bath salts” last year.
